Engineering Selection Recommendations

The BAS85,115 manufactured by Nexperia USA Inc. is the direct functional equivalent for the obsolete BAS85 L0. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters—reverse voltage rating, forward current capacity, forward voltage drop, reverse leakage current, and capacitance—are identical or within acceptable tolerance margins.

Package Compatibility: Both components utilize identical Surface Mount Mini MELF packaging (DO-213AC, SOD-80), ensuring direct PCB footprint compatibility without layout modification.

Compliance Alignment: The BAS85,115 maintains RoHS3 compliance and MSL 1 rating, matching the environmental and regulatory requirements of the original part.

Product Status Advantage: The BAS85,115 carries active product status with Nexperia USA Inc., providing assured long-term availability and supply chain continuity compared to the obsolete BAS85 L0.

Reverse Leakage Tolerance: The BAS85,115 exhibits reverse leakage current of 2.3 µA at 25 V, compared to 2 µA for the BAS85 L0. This 0.3 µA variance remains within acceptable engineering tolerance for Schottky diode applications in this current class.

Frequently Asked Questions (FAQ)

Q: Can the BAS85,115 be used as a direct replacement for the BAS85 L0 without circuit modification?

A: Yes. The BAS85,115 is electrically and mechanically equivalent. Both components share identical voltage ratings (30 V), current ratings (200 mA), forward voltage characteristics (800 mV @ 100 mA), and Surface Mount Mini MELF packaging. No circuit redesign is required.

Q: What is the significance of the reverse leakage current difference between the two parts?

A: The BAS85,115 exhibits 2.3 µA reverse leakage at 25 V compared to 2 µA for the BAS85 L0. This 0.3 µA difference is negligible in practical applications and falls within standard manufacturing tolerance for Schottky diodes in the 200 mA class. Both values are sufficiently low for typical rectification and switching applications.

Q: Are there any packaging or handling differences between the BAS85 L0 and BAS85,115?

A: Both components are packaged in Surface Mount Mini MELF (DO-213AC, SOD-80) format with identical MSL 1 (unlimited moisture sensitivity) ratings. Handling, storage, and soldering procedures are identical.

Q: Why is the BAS85,115 preferred over the obsolete BAS85 L0?

A: The BAS85,115 carries active product status with Nexperia USA Inc., ensuring ongoing availability, supply chain support, and manufacturing consistency. The BAS85 L0 is classified as obsolete, presenting procurement risk and potential discontinuation of supply.

Q: What applications are suitable for the BAS85,115 as a BAS85 L0 replacement?

A: The BAS85,115 is suitable for all applications originally designed for the BAS85 L0, including low-voltage rectification, switching circuits, and signal detection in consumer electronics, industrial control, and telecommunications equipment operating at 30 V or below with current requirements up to 200 mA.

Q: Are there any compliance or certification differences?

A: No. Both the BAS85 L0 and BAS85,115 are RoHS3 compliant and REACH unaffected. Regulatory and environmental compliance requirements are identical.
